Daily F2L #1

Case 1

Setup: R U R' U' (sexy move)

Most important solution: U R U' R' (anti sexy)

Angles: Easy from FR + BL. Harder from FL + BR.

Explanation: A trivial 3-4 move insertion from the FR/BL. From the FL/BR, most people would do a cube rotation and use one of the FR/BL algorithms. You can use fancier algorithms that use r, l, F, or M moves if you want to avoid a cube rotation altogether.

This is one of the four most fundamental cases (along with cases 2-4). Most F2L cases are solved by reduction to cases 1-4.
